摘要
目的探讨彩色多普勒超声在诊断睾丸肿瘤中的应用价值。方法回顾性分析经手术切除、病理证实的78例睾丸肿瘤的彩色多普勒超声特征,从形态、内部回声、血流情况及阻力指数(RI)等方面综合分析。结果本组患者病理结果为生殖细胞肿瘤64例:精原细胞瘤39例,非精原细胞肿瘤25例,其中混合型肿瘤9例、恶性畸胎瘤3例、卵黄囊瘤6例及胚胎癌7例;非生殖性肿瘤14例:非何杰金肿瘤13例和鳞癌1例。睾丸肿瘤超声表现睾丸内多有大小不等、形态不一的肿块,各型肿瘤有不同的声像图特点。生殖性肿瘤与非生殖性肿瘤的RI分别为0.542±0.085和0.429±0.089,两者比较差异有统计学意义(P<0.05)。结论睾丸肿瘤RI偏低,而生殖性肿瘤的血流RI多高于非生殖性肿瘤。根据睾丸肿块高频彩色多普勒声像图表现,结合临床资料能初步判断肿块病理性质,可作为睾丸肿瘤首选的影像学检查方法。
Objective To explore the application value of color Doppler ultrasound in diagnosis of testicular tumors. Methods The color Doppler ultrasonographic appearances of 78 cases of testicular tumors confirmed by pathology were retrospectively analyzed. The shape, internal echo, color blood flow and resistance index （RI） of the lesions were compared. Results There were 64 patients with germ cell tumors ： 39 cases of seminoma, 25 eases of non-germ cell tumors, including 9 cases of mixed tumors, 3 cases of malignant teratoma, 6 cases of yolk sac tumor and 7 cases of embryonal carcinoma. There were 14 cases of non-reproductive tumor： 13 cases of non- Hodgkin＇s tumor and 1 case of squamous cell carcinoma. Testicular tumors showed mass with different sizes and shapes, various types of tumors have different uhrasonography characteristics. The RI of germ cell tumor and non - germ cell tumor was 0. 542 ± 0.085 and 0. 429 ± 0.089 respectively. There was significant difference （P 〈 0.05）. Conclusion The RI of testicular tumor is low, it is higher in germ cell tumor than in non - germ cell tumor. Pathology character of testicular tumor can be preliminarily diagnosed by combining the clinical data with high frequency color Doppler ultrasound appearance, which can be used as the preferred imaging modality for testicular tumor.
